Washington Post: “Throughout his public life, Trump has pitted one group of Americans against another and inserted himself in racial controversies… As he leads his party into the potentially perilous midterm election five months from now, Trump is trying to make cultural identity a central theme of the Republican pitch to voters. His messages have been amplified by his surrogates as well as by friendly broadcasters on Fox News Channel and elsewhere in the conservative media.”

“Trump is calculating that by playing to people’s fears and anxieties he can maximize turnout among hard-core supporters to counterbalance evident enthusiasm on the Democratic side. Fueling Trump’s approach, advisers say, is an unremitting fear of his own: that his base could abandon him if he is deemed too weak on immigration, which was a centerpiece of his 2016 campaign.”
